In this implementation of the library, ``BOOST_MPL_LIMIT_UNROLLING`` has a default value of 4. To override the default, define ``BOOST_MPL_LIMIT_UNROLLING`` to the desired value before including any library header. |preprocessed headers disclaimer| Example ------- Except for overall library performace, overriding the ``BOOST_MPL_LIMIT_UNROLLING``\ 's default value has no user-observable effects.
